UNITED STATES ANDREW LARSEN, OF FOX LAKE, ILLINOIS.

BOW-FACING one.

Application filed April 25, 1923.

To all whom it may concern:

Be it known that T, ANDREW LARSEN, a citizen of the United States,residing at Fox Lake, in the county of Lake and State of Illinois, haveinvented certain new and useful Improvements in Bow-Facing Oars, ofwhich the following is a specification, reference being had to theaccompanying drawings, and to the reference characters marked thereon,which form a part of this specification.

This invention relates to bow-facing oars and consists in the devicesand combination of devices herein illustrated, described and claimed.

In that form in which I have chosen to embody my invention asillustrated in the accompanying drawings:

Fig. 1 is a plan view of a row boat equipped with my invention.

Fig. 2 is a detail plan view showing one oar in position, the drawingbeing on a larger scale.

Fig. 3 is an elevation of the detail, looking from the inside of theboat in the vertical plane indicated by the dotted line 3--3 of Fig. 2.

Fig. 4 is a vertical sectional view, enlarged, of another detail, thesection being taken in the plane indicated by the dotted line 44 of Fig.2.

5 is aside view, partly in vertical section, also enlarged, of thehandle portion of the oar and its mounting, the section being taken inthe plane indicated by the dotted line 5-5 of Fig. 2.

Fig. 6 is a perspective View, enlarged, of one of the oar locks.

In said drawings, a row boat of conventional design is indicated as awhole at A, the oar lock block at a, on each gunwale b. In each block aare two spaced apart vertical openings 1, 1, each lined with a brass,tubular bearing member 2. The oar lock shown detached in Fig. 6,comprises a casting B, preferably of malleable iron, having a bearingshank 3 adapted to fit vertically within the bushing 2, and a somewhatenlarged head 4. This head is recessed from its outer end to form asocket bearing 5 for the ball 6, hereinafter described and also has a U-shaped slot 7 cut through its side wall, as shown clearly in Figs. 5 and6. The shank 3 is horizontally bored at 8 to receive a removable lockingpin 9, which is passed through the block a and holds the casting SerialNo. 634,426.

B in position. It is to be noted that the relation of the bore 8 and theslot 7 are such as to cause the slot to face the inside of the boat whenthe casting B isin position for use. A chain 10 or other device may beused to fasten the locking pin 9 to the boat.

The oar is in two parts, the handle member as a whole being designatedby the letter C and the blade member as a whole by the letter D. Thesemembers are each provided with a casting E, carrying a ball 6 by whicheach is operatively supported on the casting B; the castings E beingsecured by rivet bolts 11 or other appropriate means. Each casting E ispositioned with respect to the end 0 or the end (i of the oar members Cand D respectively, so that itsprojecting lug member 12 will extendbeyond said ends 0 and 03, thereby affording means for attachment tolink F, the ends of which are pivotally connected to the lugs 12.

This pivotal connection is shown more fully in Fig. 4 and consists ofthe following details. A bearing stud 13 rises integrally from one faceof the lug 12, its lower rounded portion being covered by a tubularbrass or bronze bushing ring 14 and its upper exterior portion beingscrew threaded as shown at 15. The link F is suitably apertured to fitover and have swinging bearing on the bushing 14, in which position thelink F is held by a crown nut 16 and an interposed washer 17. A lockingor keeper nut 18 on the stud 13 bears upon a washer 19, a lug 20 bentdownwardly from the washer- 19 entering one of the top recesses in thecrown nut 16. It will be noted that the lower marginal part of the locknut 18 is recessed at 21 and a lug 22 on the washer 19 is bent upwardlyto fit one of said recesses after the keeper nut 18 has been screwedfirmly in position. From this description it will be manifest that, onceset, the nuts will not work loose in use and that there will besufficient play to permit the necessary relative movement of the linkend on the lug 12.

The ball 6 is integrally joined to the casting E by a conical shapedconnecting neck 23, the latter being relatively small in diameter nearthe ball 6. The head 4 of the casting B is chamfered away at 24 toreceive the neck 23 and afford a bearing therefor when, in use, theblade member D is tilted to dip into the water. This cut-away portion 24is therefore complemental in shape to the exterior surface of the neck23 and it i'slocated diametrically opposite the slot 7. The latter issufficiently large to permit the neck 28 to loosely rest the-rein Whenit is desired to remove the member D from the Water and to ship ears inthe boat A, as indicated in Fig. 0, and in dotted lines in Fig. 5. I

The bearing stud 13 is provided With a vertical oil cup aperture 25 toreceive cotton Waste 26 or other suitable packing and the lower end ofthis aperture is provided With a radial conduit 27 leading through theside Wall of the roundedlower portion of said stud 13. Oil or' othersuitable lubricant poured into the aperture 25 Will therefore find itsWay to the interior of the bushing 14 and thence to the other adjacentbearing surfaces to prevent rusting and facilitate easy movements ofthese parts.

From the foregoing it will be clear that a person seated in the boat Itmay grasp the handles 28 of the ear member C and manipulate same to dip,pull, feather, recover, dip, pull, &c., in the conventional manic..- ofrowing, While facing the bOW of the boat, and that the parts constructedas shown and described Will operate perfectly, easily and Withoutbinding or cramping.

It Will further be observed that the blade 29 of the ear member D, whileit may be dipped in the Water, Will not be so di J-ped as to place theblade unnecessarily deep in the Water, because the extent ofinclinationof the member D is limited by having the neck 23 contact With thecut-away portion 24 of the head 4.

I claim as my invention:

1. A bow-facing oar comprising a handle member and a blade member, acasting secured to the handle member having an inte gral lug projectingbeyond the end of the handle member, a ball, a tapered neck connectingthe ball with the under side ofsaid casting, a similar casting securedto the adjacent portion of the blade member, a link pivotally connectingthe two castings through their respective projecting lugs, a pair of oarlocks for said castings, each having a socket bearing for the ball, andcooperating means on the casting and ear lock for limiting the amount ofdip given to the blade member.

2. A bow-facing oar comprising a handle member and a blade member, acasting sc- =cured to the handle member having an. intetgral lugprojecting beyond the end of the handle member, a ball, a tapered neckconnecting the ball with the under side of said casting, a similarcasting secured to the ad jacent portion of the blade member, a linkpivot-ally connecting the two castings through their respectiveprojecting lugs, 11 pair of ear locks for said castings, each h aving asocket bearing for the ball and cooperating means on the casting and earlock permitting the casting member to swing into a position at rightangles with the longitudinal or vertical axis of the car lock.

3. A bow facing oar comprising a handle member, blade member, a castingsecured to each member, a link member connecting the two castings, eachcasting being provided with a projecting hall member, a pair of oarlocks each having an enlarged head member recessed to -form a socketbearing for the ball member, and provided with a Ushaped longitudinallydisposed slot cut through its side wall.

In testimony that I claim the foregoing as my invention I afiiX mysignature in the presence of two Witnesses, this 23rd day of April,1923.

ANDREW LARSEN.
